Description of the Related Art In hospitals, food factories, etc., acid water and alkaline water supplied by a water supply / drainage facility such as a hand washing area or a sink are used for sterilization / disinfection / washing of workers' hands / arms or equipment used. Often used. However, if these are drained as they are after use, many problems occur due to their acidity or alkalinity. Particularly in the case of acidic water, the effect of corroding a drain pipe made of cast iron or the like was great. For this reason, conventionally, a method of diluting the acidic water and the alkaline water with water after use and then draining the same is usually used.
Since about 11 is used, a large amount of water is required to dilute it to a safe concentration, and waste of water becomes a problem.
Moreover, since a large amount of water is supplied, it takes a long time to process.

水される。In the water supply / drainage facility of the present invention, when the supplied acidic water or alkaline water is used and discharged, if acidic water is used, neutralizing alkaline water is supplied from the supply means in the middle of the discharge route. After being supplied, it is surely mixed and neutralized by the downstream mixing means, and then discharged as neutral water. Although alkaline water may be discharged as it is, the effect of corroding the drainage pipe is negligible. In a configuration in which a neutralization tank is provided and neutralization water is supplied to the neutralization tank according to each water supply, the water supply valve is opened to supply acidic water or alkaline water, and at the same time, the neutralization water The valve is also opened and the neutralizing tank is supplied with neutralizing alkaline water or acidic water. The used acidic water or alkaline water is drained to the neutralization tank, so that it is mixed and neutralized with the neutralizing alkaline water or acidic water in the neutralization tank. The neutralized water in the tank is finally drained from the drain port.
